Transcript of "Bluetooth Jammer"

  1. 1. BLUETOOTH JAMMER
  2. 2. AIM This is a most high tech and advanced project that shows the real working model of a blue tooth signal jammer system.This system is being used world wide to prevent act of theft where the remote located cellphone or laptop is used to transfer the data.
  3. 3. COMPONENTS Microcontroller(AT89C51) Bluetooth module Frequency hopping Generator 2.4 GHz modulator MMIC Harmonic filter Whip Antenna
  4. 4. BLOCK DIAGRAM Wideband Microwave RF Trigger Detector Amplifier Mixer DC Hopping 2.4GHz Level MMIC strip Frequency Modulator line adjust Micro Generator controller RF Range Noise Generator LCD Antenna Harmonic Power filter Amplifier 50-ohm strip line
  5. 5. BLUETOOTH Bluetooth is a de facto standard and specification for small-form factor, low-cost, short range radio links between mobile PCs, mobile phones and other portable devices. The technology allows users to form wireless connections between various communication devices, in order to transmit real-time voice and data communications.
  6. 6. •The Bluetooth radio is built into a small microchip and operates in the 2.4Ghz band, a globally available frequency band ensuring communication compatibility worldwide. It uses frequency hopping spread spectrum, which changes its signal 1600 times per second which helps to avoid interception by unauthorized parties.
  7. 7. • Bluetooth wireless technology is a low-cost, low-power, short-range radio technology for mobile devices and for WAN/LAN access points. • Currently, over 2000 companies support and adopted the Bluetooth technology, which highlights the fact that Bluetooth is quickly becoming one of the low-cost wireless technologies being adopted for personal area networks. • Bluetooth makes it possible to transmit signals over short distances between broadband access devices, telephones, PCs, information appliances and other devices. • Upon introduction, the adoption rate of the Bluetooth technology was quite slow, but as the technology grows and as more companies in consumer digital electronics, cellular phones and automotive electronics produce Bluetooth- enabled products, more consumers will be intrigued by the technology and how it can benefit them in this wireless age of communication.
  8. 8. MICROCONTROLLER It is 8-bit micro controller It has 40 pin IC. It has 2 timers,5 interrupts. It occupies 250 instructions. It carries assembly and high level codings. Operating voltage is 5V.
  9. 9. FREQUENCY HOPPING GENERATOR Bluetooth adapts frequency hopping technology. Here the frequency spectrum is varied 1600 signals per second. Since that the interception and anti jamming capability will be increased.
  10. 10. 2.4 GHz MODULATOR It modulates bluetooth signal in the range of 2.4 to 2.48 GHz. It uses PN sequence generator to produce carrier signal with the high frequency range. Frequency hopping is classified into two types,1.fast frequency hopping 2.slow frequency hopping
  11. 11. MMIC MMIC stands for Monolithic Microwave Integrated Circuit. It helps to integrate the frequencies in the range of GHz. The fabrication is done VLSI technology.
  12. 12. HARMONIC FILTER It uses RFC choke and capacitor for critical coupling. It rejects first and second order distortions. It carries filter coefficients according to the distortions.
